Kafka Quickstart

1.Download the code

tar -xzf kafka_2.11-0.9.0.0.tgz

2.Start the server

bin/zookeeper-server-start.sh config/zookeeper.properties
bin/kafka-server-start.sh config/server.properties &

3.Create a topic

创建名为test的topic,1个分区分别存放数据,数据备份总共1份:

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

查看topic列表:

bin/kafka-topics.sh --list --zookeeper localhost:2181

4.Send some messages

kafka命令发送数据:

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

5.Start a consumer

kafka命令接收数据:

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

6.Setting up a multi-broker cluster

cp config/server.properties config/server-1.properties
cp config/server.properties config/server-2.properties

server-1.properties

    broker.id=1
    listeners=PLAINTEXT://:9093
    log.dirs=/tmp/kafka-logs-1

server-2.properties

    broker.id=2
    listeners=PLAINTEXT://:9094
    log.dirs=/tmp/kafka-logs-2
bin/kafka-server-start.sh config/server-1.properties &
bin/kafka-server-start.sh config/server-2.properties &
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topic my-replicated-topic
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic my-replicated-topic
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic test
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic my-replicated-topic
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --from-beginning --topic my-replicated-topic
ps aux | grep server-1.properties
kill -9 7564
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic my-replicated-topic
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --from-beginning --topic my-replicated-topic

7.Use Kafka Connect to import/export data

echo -e "foo\nbar" > test.txt
bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties config/connect-file-sink.properties
cat test.sink.txt
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic connect-test --from-beginning
echo "Another line" >> test.txt

Windows

server.properties

log.dirs=D:\\kafka_2.10-0.9.0.1\\kafka-logs

log4j.properties

kafka.logs.dir=D:\\kafka_2.10-0.9.0.1\\logs

cmd

bin\windows\kafka-server-start.bat config\server.properties
bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testCmd
bin\windows\kafka-topics.bat --list --zookeeper localhost:2181
bin\windows\kafka-console-producer.bat --broker-list localhost:9092 --topic testCmd
bin\windows\kafka-console-consumer.bat --zookeeper localhost:2181 --topic testCmd

Setting up a multi-broker cluster

server-1.properties

    broker.id=1
    listeners=PLAINTEXT://:9093
    log.dirs=D:\\kafka_2.10-0.9.0.1\\kafka-logs-1

server-2.properties

    broker.id=2
    listeners=PLAINTEXT://:9094
    log.dirs=D:\\kafka_2.10-0.9.0.1\\kafka-logs-2
bin\windows\kafka-server-start.bat config\server-1.properties
bin\windows\kafka-server-start.bat config\server-2.properties
bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topic my-replicated-topic
bin\windows\kafka-topics.bat --describe --zookeeper localhost:2181 --topic my-replicated-topic
bin\windows\kafka-topics.bat --describe --zookeeper localhost:2181 --topic test
bin\windows\kafka-console-producer.bat --broker-list localhost:9092 --topic my-replicated-topic
bin\windows\kafka-console-consumer.bat --zookeeper localhost:2181 --topic my-replicated-topic
wmic process where "caption = 'java.exe' and commandline like '%server-1.properties%'" get processid
taskkill /pid 6016 /f
bin\windows\kafka-topics.bat --describe --zookeeper localhost:2181 --topic my-replicated-topic
bin\windows\kafka-console-consumer.bat --zookeeper localhost:2181 --topic my-replicated-topic
